The DNO/OT/PE department of CNES is responsible for the production and provision of these OSO maps in collaboration with the CESBIO within the framework of Theia Land Cover SEC.

The 2019 map is available free of charge on theia.cnes.fr along with the 2016, 2017 and 2018 maps. For now, only the raster version (entire Metropolitan France in GeoTif format) is available. The vector files (broken down by department, ESRI Shapefile format) should be available soon.
